Vari-Flex® XC Rotate™

Vari-Flex® XC Rotate™

Lightweight and easy to fit, the foot incorporates a torsion cell, which helps to reduce rotary forces on the knee joint and shear forces on the residual limb.

Designed to accommodate hiking and other high impact activities, as well as level ground walking, Vari-Flex XC Rotate is ideal for active people who want to use a single, lightweight foot for a wide range of everyday activities.

Impact Levels

Impact Level

Example

Low

Daily activities involving gentle, steady walking with the use of a walking aid.

Example: Moving around at home, modest walking in the community.

Moderate

Daily activities involving average walking with the ability to vary speed or walking pattern.

Vari-Flex® XC Rotate™ Features

Active Tibial Progression

Vertical forces generated at heel contact are stored and translated into a linear motion described as Active Tibial Progression. This action reduces the need to actively push the body forward using the contralateral foot and also equalizes stride length.

Benefit: More natural gait and reduced walking effort.

Full Length Toe Lever

The full length keel/toe lever matches the length of the sound foot, providing improved support to the prosthetic limb during late stance. It ensures that users spend equal time on the prosthetic foot and natural limb, thus providing improved walking dynamics and reduced impact to the sound limb.

Proportional Response

The layering of carbon fiber, optimized through extensive computer analysis and mechanical testing, ensures that the deflection of the carbon fiber heel and forefoot components are proportional to the user’s weight and impact level.

Rotation

Trunk rotation is essential for good gait dynamics. If rotation is limited by loss of joints and the prosthetic interface, gait dynamics and comfort are compromised. Rotational forces are translated to more proximal joints and to the residual limb. Rotary torque absorbing components assist in restoring rotation thus improving joint health, comfort and gait dynamics.

Vertical Shock Pylon

The vertical shock pylon reduces impact to the residual limb, joints and lower back during daily activities. It also ensures a more energy-efficient gait by minimizing vertical displacement of the center of gravity.

Benefit: Protection of joints, the spine and stump by reduction of the shock loading.
